Description

Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a suturing and puncturing device. Background Art

[0002] A suturing puncture instrument is a commonly used surgical instrument. Patent publication CN215306503U discloses a puncture suturing device, in which two bendable folding soft sleeves (which can be switched between a straight line and a V-line) are arranged on the suturing device. During use, the two folding soft sleeves need to be switched between a straight line and a V-line. When the folding soft sleeves are distributed in a straight line (this state is shown in the attached figure of the document), the folding soft sleeves are tightly attached to the suturing device (the attached figure number in the document is 3), and when the folding soft sleeves are distributed in a V-line (this state is shown in the attached figure of the document), the device of this structure needs to switch between a V-line state and a straight line state during use, and the folding soft sleeve is directly fixed at the end of the telescopic rod. Therefore, during the process of the folding soft sleeve changing from a straight line state to a V-line state, the swing angle of the folding soft sleeve is relatively large, which easily causes the folding soft sleeve and the telescopic rod to loosen.
